[摘要]:Starting from the corresponding sulfides, N-cyano sulfoximines can easily be accessed under metal-free conditions via the corresponding N-cyano-substituted sulfilimines. The reaction sequence involves a sulfide imination with cyanogen amide in presence of a base and N-bromosuccinimide (NBS) followed by an m-chloroperoxybenzoic acid (MCPBA) mediated oxidation of the resulting sulfilimine intermediates. |
